(b)

[Debug]

The [Debug] menu provides the following items and functions (default).

Download		Downloads the specified file(s) into the debug tool currently selected in the active project. If CS+ is disconnected from the debug tool at this time, it is automatically connected to the debug tool before a download is executed. This item is disabled during program execution/build (not including rapid build) execution.
Build & Download		Builds a project and executes a download to the debug tool currently selected in the active project after the build is complete. If CS+ is disconnected from the debug tool at this time, it is automatically connected to the debug tool before a download is executed. This item is disabled during program execution/build (not including rapid build) execution. When the build has failed, download will not be executed.
Rebuild & Download		Rebuilds a project and executes a download to the debug tool currently selected in the active project after the rebuild is complete. If CS+ is disconnected from the debug tool at this time, it is automatically connected to the debug tool before a download is executed. This item is disabled during program execution/build (not including rapid build) execution. When the rebuild has failed, download will not be executed.
Connect to Debug Tool		Connects to the debug tool currently selected in the active project. This item is disabled while connected to the debug tool, during build (not including rapid build) execution or if the version of compiler being used is not supported by CS+.
Hot Plug-in [E1][E20]		Connects to the debug tool currently selected in the active project via the hot plug-in function, in order to debug the target system currently running (see "2.4.3 Connect to the debug tool using hot plug-in [E1][E20]"). This item is disabled while connected to the debug tool.
Upload...		Opens the Data Save dialog box to save the memory contents. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
Disconnect from Debug Tool		Disconnects from the currently connected debug tool. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.

	RL78 IECUBE	Uses IECUBE as the debug tool.
	RL78 E2	Uses E2 as the debug tool.
	RL78 E2 Lite	Uses E2 Lite as the debug tool.
	RL78 E1(Serial)	Uses E1 with serial communication method as the debug tool.
	RL78 E20(Serial)	Uses E20 with serial communication method as the debug tool.
	RL78 EZ Emulator	Uses EZ Emulator with an evaluation kit and so on.
	RL78 COM Port	Uses COM Port as the debug tool.
	RL78 Simulator	Uses Simulator as the debug tool.
Stop		Forcibly stops the program currently being executed. This item is disabled when the program is already halted or disconnected from the debug tool.
Go		Executes the program from the current PC position. Execution of the program will be stopped when the condition of a set break event is met. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
Ignore break and go		Executes the program from the current PC position. Execution of the program continues, ignoring set break events and action events. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
Step In		Executes the program step by stepNote from the current PC position (Step in execution). However, in the case of a function call, the program is stopped at the beginning of the function having been called. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
Step Over		Executes the program step by stepNote from the current PC position (Step over execution). In the case of a function call by the CALL instruction, all the source lines/instructions in the function are treated as one step and executed until the position where execution returns from the function (step-by-step execution will continue until the same nest is formed as when the CALL instruction has been executed). In the case of an instruction other than CALL, operation is the same as when [Step In] is selected. This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
Return Out		Executes the program until execution returns from the current function (or returns to the calling function)Note(Return out execution). This item is disabled during program execution/build (not including rapid build) execution or when disconnected from the debug tool.
CPU Reset		Resets the CPU (does not execute a program) This item is disabled during build (not including rapid build) execution or when disconnected from the debug tool.
Restart		Resets the CPU and then executes the program from the reset address. This item is disabled during build (not including rapid build) execution or when disconnected from the debug tool.
Rewind debug tool state		Rewinds the debug tool to the last state that was automatically saved. Note that the data to be rewound is limited to memory and register values that can be read or written. To use this debugging function, it has to be set so in the Option dialog box.
Save debug tool state		The following menus are relevant to saving and restoring of the state of the debug tool. Note that the data to be saved is limited to memory and register values that can be read or written.
	Restore debug tool state n	Restores the state of the debug tool from the n-th data file.
	Save debug tool state n	Saves the current state of the debug tool in a file as the n-th data.

Note	Step execution can be carried out either in units of source lines or in units of instructions. For details, see "2.7.3 Execute programs in steps".

(2)	Debug toolbar

The debug toolbar includes the buttons that control the execution of programs.

The debug toolbar provides the following buttons and functions (default).
